How many FX units can be used at one time?
It’s possible to have a huge number of simultaneous FX Units active at the same time in one instance of Omnisphere. Any of the FX Units can be put into one of the 4 slots in an Omnisphere FX Rack, plus the 5 Multi racks. Up to 53 FX Racks can be open at once.

Here’s the structure:

  • 4 Effects per Rack x 6 racks per part = 24 Effects per Part
  • 24 Effects per Part x 8 Parts = 192 FX

PLUS:

  • 4 Effects per Rack x 4 Multi AUX racks + MASTER rack = 20 FX Units per MULTI

This equals 212 possible simultaneous FX Units (depending on your computer’s capability).

NOTES ON USING THE FX

  • Each FX Unit consumes different amounts of additional CPU power, so the number of simultaneous FX Units depends on the available CPU power of your computer. Some FX, like the PRO-Verb, can use more CPU power, depending on which settings are used.
  • To maximize CPU performance in multi-timbral, LIVE, or STACK applications, it’s recommended to Bypass any Part FX Units which can be shared by other Parts (especially reverbs and delays). A good approach is to copy a Part FX Unit’s settings, bypass it and then paste the settings into a free Aux rack for shared use by the multi-timbral Parts. In other words, the signal from multiple Parts can be sent to one FX unit. Think of a hardware recording console, where the signal from multiple channels is sent through one hardware reverb.
  • Some FX Units have two pages. The second page parameters can be reached by clicking the arrow on the right side of the plug-in. Usually, it’s labeled “MORE” or indicates the parameters found on the second page.
  • You can also use external third-party FX plug-ins with Omnisphere by utilizing the multiple outputs feature of Omnisphere with your host.
